Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479926, here are decompositions:

97 + 31479829 = 31479926
109 + 31479817 = 31479926
157 + 31479769 = 31479926
229 + 31479697 = 31479926
277 + 31479649 = 31479926
307 + 31479619 = 31479926
337 + 31479589 = 31479926
349 + 31479577 = 31479926

Showing the first eight; more decompositions exist.
